The daily rTNSS was the average of the AM (morning) and PM (before bed time) rTNSS assessments. Each rTNSS assessment comprised the sum of the three nasal symptom scores for rhinorrhea, nasal congestion and postnasal drip where each symptom was scored on a scale of 0 (no symptoms) to 3 (severe symptoms).. The severity of symptoms was defined as 0: none-symptom was not present, 1: mild-sign/symptom was clearly present but minimal awareness; easily tolerated, 2: moderate-definite awareness of sign/symptom that was bothersome but tolerable, 3: severe (sign/symptom was hard to tolerate; causes interference with activities of daily living and/or sleeping. Change from Baseline was calculated as any post-Baseline value minus the Baseline value. Baseline visit was 4 days prior to randomization (Day 1).
The TNSS was the sum of the individual symptom scores for rhinorrhoea, nasal congestion and post-nasal drip which was scored on a scale of 0-3 (total score 0-9). The severity of symptoms was defined as 0: none-symptom was not present, 1: mild-sign/symptom was clearly present but minimal awareness; easily tolerated, 2: moderate-definite awareness of sign/symptom that was bothersome but tolerable, 3: severe (sign/symptom was hard to tolerate; causes interference with activities of daily living and/or sleeping. The rTNSS was a rating of the severity of symptoms over the previous 12 hours and was performed in the morning (AM rTNSS) and evening (post meridian \[PM\] rTNSS). The daily rTNSS was the sum of two assessments. The Baseline daily rTNSS was defined as the average of the daily rTNSS over the 4 consecutive 24-hour periods prior to randomization, including the assessment on the morning of randomization. Change from Baseline was calculated as the on-treatment value minus the Baseline.
Pulmonary function was measured by FEV1, defined as the maximal amount of air that can be forcefully exhaled in one second. FEV1 was measured electronically by spirometry. Trough FEV1 was the evening pre-dose, pre-rescue bronchodilator FEV1 measurement taken on Day 28 of the relevant treatment period. The analysis was performed using mixed model analysis of covarience (ANCOVA) with fixed effects of treatment, period, sex, and age. Participants were fitted as a random effect, and the period Baseline measurement was included as part of a bivariate response.
Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcibly exhaled from the lungs in one second. Pre-dose and pre-rescue bronchodilator (albuterol/salbutamol) trough FEV1 (the measurement of FEV1 performed at the end of the dosing interval) was measured electronically by spirometry in the evening at the Baseline (BL) through Week 8 clinic visits. The highest of 3 technically acceptable measurements was recorded. The Visit 3 FEV1 assessment was used as the Baseline value. Change from Baseline in trough FEV1 was calculated as the value at Week 8 minus the value at Baseline. The analysis was performed using an Analysis of Covariance (ANCOVA) model with covariates of Baseline trough FEV1, country, sex, age, and treatment group.

GW685698X is an investigational small molecule being developed for respiratory conditions, specifically allergic rhinitis and vasomotor rhinitis. Clinical trials have evaluated it for perennial allergic rhinitis, seasonal allergic rhinitis, and vasomotor rhinitis in adults, adolescents, and pediatric patients as young as 2 years old.
GW685698X is being developed by GSK plc, a global pharmaceutical company traded on the New York Stock Exchange under the ticker GSK. The company has conducted multiple clinical trials of this investigational nasal spray for allergic rhinitis indications.
GW685698X is in Phase 2 clinical development. While several completed trials are registered as Phase 3, the overall development program is currently in Phase 2. The drug is investigational and has not been approved by regulatory authorities for any indication.
GW685698X has been studied in nine completed trials with a total enrollment of 2,810 participants. Key trials include NCT00103454 in perennial allergic rhinitis, NCT00107757 in seasonal allergic rhinitis in pediatric subjects, NCT00108914 in perennial allergic rhinitis in pediatric subjects, and NCT00224523, a long-term safety study using nasal biopsy.
GW685698X is the investigational code name for the drug also known as fluticasone furoate. It is a corticosteroid nasal spray developed by GSK plc for the treatment of allergic rhinitis and vasomotor rhinitis. The drug has been evaluated in adults, adolescents, and children.
